I'm going with a snow. I'm assuming you got it at PetSmart since they sell "fancy corn snakes", but I'd be very surprised to see something besides an amel, anery, snow, or ghost there. Besides it would be extremely hard to tell if it was "bubble gum" until it was an adult as a bubble gum corn shows lots of pink and/or green as an adult. It's also very hard to tell with photographs.
So for now, I'd just call your new baby a snow. And a cute one at that
